Fig.V 7 is a diagrammatic view showing the electric circuit.

A at, circular, heavy base 10 is supported upon a floor 12, and may bebolted thereto if desired. Centrally of the base, an upwardly opening,cylindrical, flanged socket 14 is bolted to the base. Threaded into thesocket is the lower end of an elongated, vertical tubular standard 16.External threads are provided on the standard intermediate its ends,said threads being closer tothe lower part has been than to the upperend of the standard.- A sleeve 18 is internally threaded for engagementwith the threads of the standard, the standard extending upwardlythrough said sleeve. On the upper end of sleeve 1S, an outwardlydirected, circumferential flange has spaced apertures receiving boltsconnected to a flat table 20 of circular outer conliguration, formed toa large diameter to permit a number of persons to be seated therearound.Table 2t) has a center opening through which standard 16 extends and ismade rigid by a plurality of supporting posts 17 having end flanges 19which are in turn secured to the top f of the base 10 and to the bottomof the table 20.

A at, circular condiment holder or Lazy Susan 22 of substantiallysmaller diameter than that of the tablev 20 is centrally provided with adepending, circular boss Patented Dec. 6, 1955 threaded to engageinternal threads on a connecting ilange 28 having a circumferentialseries of apertures receiving bolts 30 passing through registeringapertures spacedV about the center opening of a ilat, horizontallydisposed, circular plate 32.

Spaced 90 apart about the outer periphery of plate 32 (Fig. 3) are anglebrackets 34 of L-shape, each having a horizontal leg bolted to andarranged radially of plate 32, and a vertical leg extending upwardlyfrom the horizontal leg. The vertical legs are apertured to receivebolts, that pass through registering apertures of a cylindrical housing36. Housing 36 is formed open at its upper and lower ends, and isvertically disposed inconcentric relation to standard 16 and plate 32.The marginal portion of the plate is in contact with the inner surfaceof the housing, intermediate opposite ends of the housing, but closer tothe lower than to `the upper end of the housing.

A circular bottom plate 38 is of a diameter equal to that of plate 32.Plate 38 is spaced from plate 32, being disposed below the plate 32 incontact with the inner surface of housing 36. Bolts 40 arranged in anannular series pass through registering openings of plates 32, 38 toixedly connect the same. Mounted in openings formed in plate 38 (Fig. 4)are vertically disposed lamp sockets 42, opening downwardly to receivedepending lamps 44, disposed to cast their beams upon the table 20.

On the upper end of standard 16 (Fig. 6) a lat, circular plug 46 of woodor the like is Seated. A vertical, tubular shaft housing 48 has apermanently closed lower end 50 engaged against plug 46, housing 48being externally threaded at its lower end to engage internal threads ofa coupling sleeve 52, thatis also engaged with the upper end of standard16. A quantity of oil 54 or other lubricant is provided in shaft housing48, and extending within the shaft housing 48 is a vertically disposed,solidly formed spindle or stub shaft 56, the upper end of which projectsabove shaft housing 48 and supports the center poitionlof a ilat,circular center plate 58 of a fan blade structure. f

A circumferential series of openings formed in center plate 58 receivesdownwardly extending connecting bolts 60, passing through registeringopenings of the horizom tally rotating pulley 62 circumposed about shafthousing 48, out of contact with the shaft housing. A belt 64 is trainedabout pulley 62, and also (Fig. 3) about ak the table top 20, andconnected in series with the motor` are the several electric lamps.Thus, a conductor 76 extends from the motor through a notch 78 formed inthe marginal part of plate 32. Cord 76 (Fig. 4) extends to one of thelamp sockets, and extending from said one lamp socket is a lead 80 tothe next lamp socket, another lead 80' being extended to the last lampsocket. A lead 82 extends from said last lamp socket into standard 16,and also extending into the standard 16 is a lead 84. Leads 82, 84 areconnected to opposite sides of a 3 switchA $6 mounted upon. theunderside of table 20 (Fig. l). l

An electric plug 87 connected to lead 76 is adapted to be plugged into areceptacle that is provided upon the motor, to. connect the switch andlamp electrically to the motor; The arrangement is such as to causemovement of the switch to on position to be eiective for closing acircuit through the. lamps a-nd motor, to operate the motor for turninga fan blade structure, simultaneously wth illumination with table 20.

The fan blade structure includes a tlat, horizontally disposed bladesupport plate 88 that overlies and is spaced above the open upper end ofhousing- 36. AV center opening of blade support plate 8S receivesdownwardly extending bolt 90 (Fig. 6) threaded into an upwardly opening,axial socketof spindle 56,. said bolt also being threaded into a centeropening of plate 58. spindle or stub shaft 56, plate S, and plate 88 areall connected for joint rotation, the bolt 90 having a washer that bearstightly against the plate 88 to bind the same against rotatable movementrelative to plate 58.

Integrally formed upon the marginal part of the plate 88 is a dependingskirt 92, formed to` an inner diameter slightly greater than the outerdiameter of housing 36, and slightly lapping the housing 36 as bestshown in Figs. 5 and 6.

Recesses 94 are formed in the skirt (Fig. 2) and extending through therecesses are fan blades 96. Four blades, spaced 90 apart, are providedin the illustrated example. However, the number can be increased ordecreased as desired.

Blades 96 are pitched obliquely to the horizontal plane in which theyrotate, so as to direct air downwardly toward the table top Blades 96are formed, intermediate their ends, with downwardly opening notches 98of rectangular shape, said. notches being provided in the lowerlongitudinal edges of the blades 96 and receiving the upper end ofhousing 36. Also formed in blades 96, at the inner ends thereof, areright-angular recesses 100 providing a clearance for the marginalportion of center plate 58.

The upper longitudinal edges` of blades 96 are integrally formed withattaching anges 102 lying in horizontal planes. Overlying anges 102 incontact therewith, and arranged longitudinally and centrally of flanges102 are downwardly facing channel bars or arms 104. Arms104 haveopenings receiving` bolts 106, passing also through registeringopenings. of flanges 102 to xedly secure the blades to the arms. Theinner ends of the arms project inwardly a substantial distance beyondthe inner ends of blades 96, and are interposedtas spacers betweenplates98, 88. Registering openings are formed in plate 88 and the inner endportions of the arms 104, receiving bolts 108- that fixedly connect` thearms to the plate 88.

By reason of the arrangement illustrated, the major portions of the fanblades are disposed externally of housing 36 to direct cooling airagainst the users of the table. However, the blades also have inner endportions, constituting the parts of the blades that extend from theinner end of the blades to the notches 98 within the housing 36, whichdirect cooling air downwardly within housing 36 against motor 68.

It is to be noted that the lubricating oil 54 sup*- ports the entire fanblade structure in the illustrated position, and of course., in acommercial embodiment, a suitable packing gland might be provided. atthe outer end of the shaft housing 48 surrounding the spindle; 56, toinsure against leakage of oil between the.A contacting surfaces of thespindle and shaft housing. The: oil, at the same time, lubricates theVstub shaft bearing. defined by housing 48, during rotation of thefanblades structure.
